The U.S. president is threatening to impose stiff tariffs on Mexican imports, but how do tariffs really work? Darren gives us the low-down. Next, Cristina looks into myths many of us believe thanks to movies and TV shows. Finally, Adam examines claims floating around social media that the Statue of Liberty was originally based on a Muslim woman.

In terms of media myths, I’ve always cut filmmakers some slack for *showing* asteroid fields as much denser than they really are, simply because a realistic presentation would not fit within the frame. As well, the spaceships are actually travelling faster than they are shown. I guess it balances out.

A similar phenomenon occurs in movies showing small infantry combat units on patrol, most notably WW II and Vietnam. I didn’t learn much in my basic “army training”, but I did learn that, conditions permitting, you’re supposed to be 5 to 10 meters apart, to make it harder to shoot you. Again, I grant artistic license to allow more actors to fit in the frame, and also to allow them to be close enough to talk to each other.
